Where did this come from?

Ok, I think this file came from a link on weblogs.asp.net, but I can't find the link, just the file.  I have a file called PerfNScale2-27-04.zip.  Inside the zip file is a bunch of good info about how to create applications with .NET that scale up and perform well.  The problem is that I can't find where this file came from.  I think it came from GotDotNet.com, but I don't know from where.  If you have that link, if you can please post it as feedback that would be awesome.
